FEED-WATER HEATER AND SEPARATOR.

Specification of Letters Patent.

Application filed August 15, 1908.

Serial No. 448,759.

To all whom it may concern:

Be it known that we, WILLIAM S. HAL- LOWELL, resident of and whose post-office address is No. 3305 Race street, city and county of Philadelphia, State of Pennsylvania, and JOSEPH WILLARD GAMBLE, resident of and whose post-office address is No. 3251 North Sixteenth street, city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Feedater Heaters and Separators, of which the following is, taken in connection with the accompanying drawings, a full, complete, and concise description.

Our invention relates to improvements in separators, and especially, though not exclusively, to combined separators and feed Water heaters, where the separator is made a part of and integral with the heater.

The objects of our invention are to provide a separator having a definite relation in point of capacity and efficiency to the heater and other elements of a heating system of which it is a part,to provide positive, convenient and efficient means for controlling and regulating the passage of the purified steam after separation, from one part of the system to another, and to provide means for diverting the steam proportionally to different parts of the system, as will be more at length pointed out hereafter. These objects we attain by the devices and arrangement described in and claimed here inafter, and illustrated in the accompanying drawings.

Figure 1 is an elevation partly in section showing the preferred form of our invention, and showing the separator forming a part of and made integrally with a feed Water heater. Fig. 2 is an elevation of a separator and a heater not integrally constructed, but connected by a suitable passage with the heater. Fig. 3, as illustrated, is a modification of my device.

Referring to the figures, 1- is the body or shell of the heater, -2 the body or shell of the separator, 3 the trays inside the heater, 4 the steam inlet to the separator, 5 the baflie plate in the separator, -6 outlet from heater, 7 out et from separator to other point of use, as a heating system, 8 passage from separator to heater, 9- seats for transfer valve, 1 O- transfer valve, 1 1* valve controlling overflow or waste from heater to separator trap,

from impurities; and heretofore where the steam has been utilized in a feed water heater for heating the feed water before passing it to the boilers, it has been customary to provide the feed water heater, (when of an open type) with a separator usually attached to and an integral part of the heater, the steam on entering the separator, and passing through the same, comes directly, without hindrance or diversion into the heater; and where it is intended that in the same installation. a portion of the exhaust steam shall pass into a heating system or to another point of use, it has heretofore been found necessary or desirable to place an extra separator in the line of exhaust steam passing to that heating system or other point of use. Two separators have thus been required to provide adequate separation for all the steam; one to perform the desired function in connection with the heater, and the other to accomplish the same end with. regard to the heating or other system. This plurality of separators, of course, has meant increased expense, complication, and loss of economy. In order to avoid these disadvantages, in our invention as disclosed herein, we provide one separator, preferably an integral part of and attached to the heater, of such size and capacity that it is capzble not only of taking care of all the steam that is required to heat the feed water for the boilers, but such as may be necessary to also serve the heating system or other installation or installations. To secure additional advantage, moreover, we provide a valve,

preferably operatii'ig at the same time to open or cut oil' the passage from the separator to the heater or to the heating system or other point or points of use, as the case may be, and thus the operation of closing one passage or passages and opening the other or others, may be performed simultaneously and inversely; that is, as one passage is closed in part or in whole, the other is opened in part or in whole or the others are opened in part or in whole.

Since the amount of steam necessary for the heating system and heater together far exceeds that necessary to heat the feed water for the boiler alone, it will be clear that a separator of sufficient size to provide for the requirements of both the heating system and heater will be larger than what would be required merely for the heater. We therefore make our separator of such size that all the steam may be passed through it to the heating system, and proportion the valve and .separator so that they will deliver to the heater the full quantity of purified steam re quired by the heater, while passing any surplus that may be, to the heating system; and also the converse, that is, to deliver the full quantity of purified steam necessary for the heating steam.

The operation of the device is as follows: The steam enters the passage 4 of the separator, passes by the baffle plate 5 into the interior chamber of the separator. Normally, the steam passes into the heater through the passage 8 past the valve 1 0 which is normally open, though shown closed in the drawing. The amount of steam required to heat the water being greater than the capacity of the heater to condense or utilize it all, the excess passes out through the passage 6 to the atmosphere. If, however, a heating system, supplied through 7 requires a supply of steam while the heater is in operation,-then since the supply passing through the heater is in excess of its requirements, the valve 10 is adjusted so as to partially close the passage *8--, and at the same time open the passage to' the outlet --7-. By adjusting this valve, the steam may be so regulated that practically only a sufficient quantity will be passed into the heater to perform the necessary heating, without excessive waste through the outlet -6, and the balance of the steam will then be deflected through the outlet 7 in the separator to the heating system or other installation. It will be evident that if desired, the heater may be entirely out off by the valve 10 giving the preference to the outlet to the heating system 7 where all the steam passes out after being passed through the separator.

Vi e do not limit ourselves to any particular type, design, location, proportion or arrangement of the device including the heater or separator or their component parts, as our invention may be carried out and embodied in structures differing in these respects from what we have illustrated in the drawings as our preferred form. Where we have used the words relative capacity as relating to the have it understood that we are not limited. to

the numb er of ports or openings leading from the separator to different points other than the heater, which other points may be controlled simultaneously, proportionately, suecessively or alternatively by a suitable valve, designed for the purpose or a plurality of valves; but

That we claim and desire to protect by Letters Patent is 1. The combination of a feed water heater; a heating system; a separator interposed between the source of steam supply and the heating system and heater, and having separate passages communicating with the heater and with the heating system, and a valve for controlling the flow of steam to either passage.

2. The combination of a heater; a separator having an outlet to the heater and an outlet to another point of use; and means for proportionally and wholly diverting the flow of steam from one outlet to the other.

3. The combination of a heater; another point of use for exhaust steam; and a separator of such relative capacity in proportion to the heater that it can supply both the heater and the point of use, and means for diverting steam to either point of use.

4. The combination of a heater; another point of use for exhaust steam; and a separator of such relative capacity in proportion to the heater that it can supply both the heater and the other point of use; and a valve for proportionally and wholly diverting the flow of steam from the heater to the other point of use.

5. Combination of a feed water heater; a separator; an outlet in said separator to the heater; a plurality of outlets from said separator to other points; and a valve for controlling the flow of steam through any of said outlets.

6. A unitary structure comprising a heater; a separator having a plurality of passages leading from the separator to the heater and elsewhere; and means for controlling the flow of steam through said passages.

7. Combination of a heater; a separator having a plurality of passages leading from the separator to the heater and elsewhere; and means for proportionally and wholly diverting the flow of steam from one passage to another, or others.

8. The combination of a heater; another point of use for exhaust steam; a separator of relatively greater capacity than the heater, provided with an outlet; said separator interposed between the steam supply and the heater and the other point of use; and means for diverting the steam supply from the heater to the other point of use, and vice versa.

9. A separator provided With a plurality of steam outlets, and a valve Within said separator intermediate and controlling said outlets.

10. A separator provided with a plurality of outlets for purified steam; a valve Within said separator for successively and proportionately closing said outlets.

11. A unitary structure comprising a heater and a separator; another point of use for exhaust steam; said separator being of such relative capacity in proportion to the heater that it can supply both the heater and the point of use.

12. A unitary structure comprising a heater and a separator provided with a baille; another point of use for exhaust steam; said separator of such relative ca pacity in pro ortion to the heater that it can supply both t 1e heater and the other point of use.
